Out-of-Band Spurious Emission Measurements

Out-of-band spurious measurements are made on signals outside the system main band. These signals, which can interfere with other communication systems, can be categorized into harmonics and random spurious emissions. Real time monitoring of spurious emissions from a transmitter can uncover unwanted signals before they interfere with other users on the other channels.

Required Equipment

￿Site Master Model S114C or S332C

￿30 dB, 50 Watt, bi-directional, DC –18 GHz, N(m) – N(f), Attenuator, 42N50A-30

￿Test Port extension cable, Anritsu 15NNF50 – 1.5C

Procedure

Step 1. Using the test port extension cable and 30 dB attenuator connect the Site Master to appropriate transmit test port.

Step 2. Press the ON/OFF key on the Site Master.

Step 3. Press the MODE key.

Step 4. Use the Up/Down arrow key to select the Spectrum Analyzer mode and press

ENTER.

Step 5. Select the center frequency for the channel of interest.

Step 6. Set the frequency span wide enough to include the primary channel and upper and lower channel.

Step 7. Set the following parameters: reference level = 0 dBm input attenuation level = auto resolution bandwidth =10 kHz video bandwidth =300 Hz.

Step 8. Use the limit line and markers to read and compare the observed signals to the specified allowable level of out-of-band spurious emissions for the correspond- ing channel transmitted frequency.
